A steering wheel includes a core and a foamed polyurethane coating that covers a ring section of the core. The foamed polyurethane coating is formed by foam molding of a polyurethane material containing 91 parts by mass of a base polyol, 10 to 25 parts by mass of a pigment, 1 to 3 parts by mass of a benzotriazole ultraviolet absorber, 0.8 to 2.5 parts by mass of a hindered amine photostabilizer, and a polyisocyanate. A total amount of the ultraviolet absorber and the photostabilizer is 2.7 parts by mass or more. The foamed polyurethane coating is in the form of an integral skin foam including a highly foamed core foam and a lowly foamed skin layer. The surface of the skin layer is not provided with a coating film formed from a coating material, and serves as a product surface that assumes a color of the pigment.
